To (ZZZ whom it may concern.

Be it known that we, WILLIAM JOSEPH BROWN, engineer, residing at '75Elmar Road, West Green Road,Tottenham, London, in the county ofMiddlesex, and JOHN ROBERT BEER, engineer, residing at26 Victoriaavenue,East Ham, London, in the county of Essex, England, subjects ofthe Queen of Great Britain, have invented certain new and use fulImprovements in Apparatus for Use in Making and Dispensing Infusions;and We do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to apparatus for use in making and dispensinginfusions, such as infusions of tea or of coffee or the like, in

shops or in cases where a considerable quantity has to be made at onetime; and the said invention has for its object to provide apparatus bymeans of which clear infusions are made and the water in the boiler isprevented from becoming contaminated by the infusions, and to generallyimprove and render such apparatus more efficient. According to thisinvention a passage for the water from the boiler to the infusing vesselor to each infusing vessel is provided separate from that or those whichleads or lead to the container. The strainer into which the Water fromthe boiler passes is situated in the upper part of the infusing vesselor vessels, the tubes sup- 5 plying the water at the upper part of thesaid infusing vessel or vessels and into the said strainer, and any furor other like impurity cannot get into the infusion when it is passedfrom the infuser or infusers into the container. To keep the Water inthe boiler at a uniform level, a feed-valve is used in a casin gsituated at any desired distance from the boiler and connected to it bytubes at top and bottom and provided with a float to regulate 5 thewater-supply, so that the float and working parts of the valve are notliable to be corroded or coated with fur or deposit, as has hithertobeen the case, because the water in the valvular arrangement beingplaced at any convenient distance from the boiler can be maintained at amuch lower temperature than that in the boiler. Moreover, thisarrangement allows of ready access being had to the valve for repair.

We will describe, with reference to the 3.0- companying drawings, anapparatus constructed in accordance with this invention provided withtwo infusing vessels and one container.

Figure 1 is a side elevation, and Fig. 2 is a sectional elevation, ofthe infusing and containing vessels'and the controlling devices inconnection therewith, these parts being conveniently situated above thecounter. Fig.

3 is a vertical section on the line 1 2, Fig. 1. i Fig. 4: is ahorizontal section on the line 3 3, Fig. 1; and Figs. 5 and 6 are partvertical sections, respectively, on the lines 5 5 and 6 6, Fig. 4. Thesection of this part shown in r Fig. 2 passes through the line 4 4, Fig.4 showing the various passages between the boiler, the infusing vessels,and the container and means for controlling them, as hereinafterdescribed. Fig. 7 shows the boiler and adjuncts connected therewith,these parts being conveniently arranged below the counter; but they mayall be in any other convenient position.

The two infusing vessels A A are supported in brackets B, projectingfrom acolumn O, which carries a container D, into which the infusion ofcoffee, tea, or other matter after being made in either of the infusersA A is passed. This container D is preferably screwed onto the column Oat d so that it can be readily removed for cleaning. The passages whichafford communication between the boiler M and either of the infusers A Aand between the infusers A A and the container D are governed by twococks E, as 0 hereinafter described.

The boiling water is forced from the boiler by the pressure of the steamtherein up the pipe a, which leads by passages a in the column O andpassages (t in the brackets B 5 and by a pipe (0 to the upper part ofeach infuser, into which it is discharged into and through a sieve orperforated box F, secured to the upper part of the infuser.Communication between the passages a and a is established by thepassages a through each of the cocks'E.

Each infuser A A is made in two parts, the upper part being hinged at bto the bracket B and secured by a catch 1) engaging with an tween thepassages ar and the pipe a eye on the bracket B, a passage beingprovided at b to establish communication be- The coffee,.tea, or othermatter from which the infusion is to be made isplaced in the lower partof the infusers, a porous material being secured at bottom by a ring orgrid b to prevent the ground coffee or the like from getting in thepassages. fusers becomes full of liquid the overflow passes through thesieve F and by a pipe 0, (see Fig. 2,) arranged by the side of the pipeafiand by a passage in the bracket B through the passage 0 in the cock Eand flows out of a pipe 0 which thus indicates that the infuser is full,the strainer preventing fur or other matter likely to clog orcontaminate the passages from passing thereinto. The cock E is thenturned from the position shown at the right-hand side of Figs. 5 and 6,so as to cut off the supply of boiling water to the infuser and theoverflow and so as to cause the passage .0 in the cock E to establishcommunication, as shown at the left hand of Fig. 5, between the passage0 and the passage 0 leading into the interiorof the column 0, which isin connection with the steam-space of the boiler by a pipe J. Steam thenpasses by the passages J, 0 0 c, and c to the top of the infuser andexerts pressure upon the surface of the infusion therein. When either ofthe cooks E is in this position, another passage 61 therein establishescommunication between the infuser A or A, as the case may be, and thecontainer D, the passage d connectinga passage d in the bracket, intowhich an opening at the bottom of theinfuser opens,

and another passage 01 in a bridge between the two casings of the cooksE. A tube g leads from this passage d to the upper part of the containerand is filled with a spreading device at 9. When, therefore, either ofthe cocks E is in the position described, the steampressure acting onthe surface of the infusion in the infuser will force it therefrom intothe container D, from which it can be drawn by the tap H on the pipe72.. The tube 9 is surrounded by another tube g closed at top, intowhich steam isadmitted from the steamspace in the column 0 to keep theinfusion hot and in proper condition.

A vent-pipe 9 leads from the upper part of the space within the tube gto a tap 9 (see Figs. 2 and l) to enable the air to escape from the saidspace.

9 is a vent. at the top of the container D to allow air and steam toescape.

I is a tap to enable boiling water to be drawn directly from the boilerwhen required, the said water rising through a pipe 11, passing throughthe steam-pipe J.

A gage K is provided to enable the amount of infusion in the containerto be ascertained.

Whenit is desirable to infuse less than a After either of the infullchargein either of the infusers-say, a quarter or half the charge-smallcocks 7c are provided in the infuser, so that when open they willindicate when the liquid has reached the required level. Cocks L arealso provided in the infusers to enable the liquid to be drawn offdirectly without first being passed into the container and also to allowthe steam to escape before the infuser is opened after the infusion hasbeen passed therefrom into the container. Referring to Fig. 7., theboiler M is shown as being heated by a ring of gas-burners N, the supplyof gas to which is controlled by an automatic device, (shown at P.) Inthis a valve p is caused to close more or less onto its seat p in thegas-passage s by the steampressure from the boiler entering by a pipe mand acting on a flexible diaphragm 'n and so regulate the quantity ofgas supplied, ac-

cording to the steam-pressure in the boiler.

the aperture 72 without passing into the gaspassages. The spring 1) actsto normally open the valve, the sensitiveness of which can be regulatedby a screw 19 A float Q is provided to automatically regulate the supplyof water to the boiler, the float being supported in a casing Q outsidethe boiler and at any desired distance therefrom and in communication attop and bottom with the boiler by pipes q q, so that the float will riseor fall, according to the level of the water in the boiler. The float isprovided with a valve (1 which when the float rises seats itself againsta seating 1 around the water-eXit from the supply-pipe R and so preventsany further supply of water to the boiler until the level again falls.

T is a cock providedwith passages to simultaneously control both thewater and gas supply through the passages R and s.

' Although we have shown two infusing vessels, it is to be understoodthat either one or two may be used; but two are generally prefenable, asthe infusions may bemade in them alternately to maintain a continuoussupply.

We claim as our invention- 1. Apparatus for making and dispensinginfusions, consisting of a boiler, an infusionchamber, a container, anda controlling-cock, having three sets of openings, one ofwhichcommunicates through passages from the water in the boiler to the top ofthe infuser, and a second through passages from the top of the infuserthrough said cock to the atmosphere both sets of said cock-openingsbeing adapted to establish communication with both sets of passages atthe same time, the third set of openings in the cock communicatingthrough passages between the container and the infuser and so placed inthe cock that they and 'a strainer into which the passage from theboiler opens and situated above the passage from the infusing vessel orvessels to the container and a casing outside the boiler and incommunication therewith at top and bottom and containing a float and avalve for regulating the inlet of water all substantially ashereinbefore described.
